Which number can you add to get a sum of 0 A . -10 B. -5 C. 0 D. 5

1 answer:

4 0

To figure this one out, my pre calculus teacher said to "plug and chug". Since you are adding each number to itself, A=-20, B=-10, C=0, and D=10. So your answer would be C.0

Rufina [12.5K]

Answer:

Budget to purchase the material for the year 2017 will be $475500.

Step-by-step explanation:

The budgeted production for 2017 is for 53000 comforters.

Estimated beginning inventory is 31000 yards.

Ending balance is 30000 yards of the material.

Therefore, expression that models the expression will be

End material = Beginning material + Material purchased - material for production

30000 = 31000 + Material purchased - (53000×6)

30000 - 31000 = Material purchased - 318000

-1000 = Material purchased - 318000

Material purchased = 318000 - 1000

Material purchased = 317000 yards

Since, material cost is given as $1.5 per yard

Therefore, Budget to purchase the material = 317000×1.5

= $475500

Budget to purchase the material for the year 2017 will be $475500

PLEASE HELP!! 20 POINTS PLUS BRAINLIEST IF YOURE RIGHT!!

zaharov [31]

Firstly, we have to find the mean. The mean is simply the average of the numbers, which we find by adding each number in the sequence and then dividing that result by the total amount of numbers.

13.3 + 14.3 + 15.3 + 16.3 + 17.3 = 76.5

76.5 / 5 = 15.3

Okay, so our average is 15.3.

Now, we have to subtract the mean from each number and then square the result.

(13.3 - 15.3)^2 = 4
(14.3 - 15.3)^2 = 1
(15.3 - 15.3)^2 = 0
(16.3 - 15.3)^2 = 1
(17.3 - 15.3)^2 = 4

Now we have to find the mean of those numbers!

4 + 1 + 0 + 1 + 4 = 10

10 / 2 = 2

Finally, we take the square root of that number and we have our standard deviation. =)

A garden is shaped in the form of a regular heptagon (seven-sided), MNSRQPO. A circle with center T and radius 25m circumscribes

Alenkinab [10]

The relationship between the sides MN, MS, and MQ in the given regular heptagon is $\dfrac{1}{MN} = \dfrac{1}{MS} + \dfrac{1}{MQ}$

The area to be planted with flowers is approximately 923.558 m²

The reason the above value is correct is as follows;

The known parameters of the garden are;

The radius of the circle that circumscribes the heptagon, r = 25 m

The area left for the children playground = ΔMSQ

Required;

The area of the garden planted with flowers

Solution:

The area of an heptagon, is;

$A = \dfrac{7}{4} \cdot a^2 \cdot cot \left (\dfrac{180 ^{\circ}}{7} \right )$

The interior angle of an heptagon = 128.571°

The length of a side, S, is given as follows;

$\dfrac{s}{sin(180 - 128.571)} = \dfrac{25}{sin \left(\dfrac{128.571}{2} \right)}$

$s = \dfrac{25}{sin \left(\dfrac{128.571}{2} \right)} \times sin(180 - 128.571) \approx 21.69$

$The \ apothem \ a = 25 \times sin \left ( \dfrac{128.571}{2} \right) \approx 22.52$

The area of the heptagon MNSRQPO is therefore;

$A = \dfrac{7}{4} \times 22.52^2 \times cot \left (\dfrac{180 ^{\circ}}{7} \right ) \approx 1,842.94$

$MS = \sqrt{(21.69^2 + 21.69^2 - 2 \times 21.69 \times21.69\times cos(128.571^{\circ})) \approx 43.08$

By sine rule, we have

$\dfrac{21.69}{sin(\angle NSM)} = \dfrac{43.08}{sin(128.571 ^{\circ})}$

$sin(\angle NSM) =\dfrac{21.69}{43.08} \times sin(128.571 ^{\circ})$

$\angle NSM = arcsin \left(\dfrac{21.69}{43.08} \times sin(128.571 ^{\circ}) \right) \approx 23.18^{\circ}$

∠MSQ = 128.571 - 2*23.18 = 82.211

The area of triangle, MSQ, is given as follows;

$Area \ of \Delta MSQ = \dfrac{1}{2} \times 43.08^2 \times sin(82.211^{\circ}) \approx 919.382^{\circ}$

The area of the of the garden plated with flowers, $A_{req}$ , is given as follows;

$A_{req}$ = Area of heptagon MNSRQPO - Area of triangle ΔMSQ

Therefore;

$A_{req}$ = 1,842.94 - 919.382 ≈ 923.558

The area of the of the garden plated with flowers, $A_{req}$ ≈ 923.558 m²
